LOOSE-LEAF BINDER.

SPECIFICATION forming part of Letters Patent No. 785,750, dated March28, 1905. Application filed December 7, 1904. Serial No. 235,823.

To all whom it may concern:

Be it known that I, PHILIP MONTGOMERY, a citizen of the United States,and a resident of Hartford, in the county of Hartford and State ofConnecticut, have invented a new and Improved Loose-Leaf Binder, ofwhich the following is a specification.

My invention relates to that class of devices employed for securingsheets of paper so that they may be readily removed and replaced at willeither separately or collectively; and the object of my invention is toprovide a device of this class that shall be simple and inexpensive inits construction; and a further object of the invention is to provide adevice that shall be extremely simple and convenient in its method ofoperation and use.

A device in the use of which the above objects may be attained isillustrated in the accompanying drawings, in which- Figure 1 is aperspective View of a binder embodying my invention. Fig. 2 is a view ofthe blank for forming the back. Fig. 3 is a view of the blank forforming the case.

In constructing a binder in accordance with my invention I provide acase which is formed to shape from ablank 1, as shown in Fig. 3 of thedrawings. This blank is preferably cut from sheet metal of properlength-and width to form when bent into the shape shown in Fig. 1 of thedrawings a case having abottom That part of the blank to form the bottomis provided with projections 4:, that are properly formed to constitutepart of a hinge. The blank is also formed as to those portions which areto form the ends with stop projections 5. When the case is finallyformed, the lugs on the bottom are bent into tubular shape to form themembers 4: of a hinge, and the stop projection is bent, preferably, atright angles to the ends 3 to form stops 5. The cover of the case isformed of a sheet of metal 6, as shown in Fig. 2 of the drawings, thispart being of proper dimensions to form when bent to shape a back 7 anda top 8, the former preferably being adapted to lie against the edge ofthe ends and bottom of the case and the latter to overlie the upper endsof the end pieces 3 of the case. Slots 9, extending laterally of thetop, are provided for the reception of pins 10, secured in the bottomportion of the case, each of the pins hearing at their outer ends abeveled portion 11. The blank forming the cover is also provided withcatch projections 12, which in final form are bent, preferably, at rightangles to the back of the cover, forming catches 12. The catches andstops are preferably of hook form, as shown in Fig. 1 of the drawings,and are adapted to engage and -interlock with each other. A lock-plate13 is hinged on the outer surface of the top 8 of the cover, beingsecured, as by means of springs 14, which serve the double purpose of ahinge to allow a slight swinging movement of the plate and also as aspring to hold it firmly against the outer surface of the cover 8. Thislock-plate is provided with openings 15, adapted to receive the pins 10.

This binder preferably includes in its construction a cover consistingof a back 16 and leaves 17, flexibly united to the back in the usualmanner.

In the normal location of the parts the leaves to be bound, having firstpreferably been perforated with holes in proper position to receive thepins 10, are located upon the pins and the cover is in its closedposition with the back 7 and the top 8 resting against the back and endedges of the case, the lockplate 13 being closed down and the pins 10passing through the slots 9 into the openings 15, which look the partsclosed. When it is desired to remove a leaf, the plate 13 is swungupward to disengage it from the ends of the pins 10. It will be notedthat in this movement to swing the plate 13 to disengage it from thepins pressure is applied to the cover in a direction to swing it as toits upper end away from the case, and this swinging movement is alsoaided by a spring 18, secured to the bottom 2 and the back 7, whichspring tends to hold the cover as to its upper end swung away from thecase. \Vhcn the cover has swung the proper distance to cause the ends ofthe pins 10 to be disengaged and to be freely accessible, the catches 12engage with the stops 5, limiting the backward swinging movement of thecover. It will be noted that the cover is thus maintained in aconvenient and accessible position to be closed when desired, the back16 being raised so that the hand may be readily placed behind it toclose the parts, the edge of the plate 13 engaging the beveled edges 11of the pins 10, causing the plate to be raised until the ends of thepins are located opposite the openings 15, when the plate swings downand locks the cover in position.

In prior devices of this class a difficulty has been experienced fromthe fact that both hands in many instances are required to release thecover from the case and when released the cover swings down flat andchiliculty is experienced in placing the hand underneath the cover toclose the device. It will be seen that by my improved construction theback is always retained in a convenient and accessible position, and thedevice as soon the lock-plate is released is selfacting to open to anextent to allow the pins to be readily accessible for the purpose ofremoving or inserting papers.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-
